2 Claims.

The present invention relates to packages and, while particularlyembodying wide mouth containers, is useful for receptacles havingpouring and lling openings of varying diameters. The container isadapted to hold and preserve contents of a fluid or pasty nature such aspaints and lacquers, chemicals, syrups and soups, as well as solid ordry materials. Preferably th package is formed of sheet metal.

The receptacle of the present invention comprises two parts, namely abody including an integral bottom at one end and at the other end anintegral sealing lip and locking shoulder for receivingr a lid, allformed from a single piece of material; the second element of thecontainer, namely the lid or cap, is likewise formed from a single pieceof material, and said body is formed with a shoulder adapted to act as apry-off shoulder for removing the cap from the body.

The container presents a relatively unobstructed pouring opening whichis highly important in that there is but negligible opportunity for thecollection of the contents at the mouth of the container and the pouringis uniform until all of 4the contents have been removed.

In addition, a very effective seal is provided in that the cap has aperipheral sealing groove receiving the sealing lip of the container anda gasket material may be interposed between the two; also the walls ofthe sealing groove resiliently engage the sealing lip to assure apermanent and effective seal. Furthermore, the skirt of the cap ispressed in at spaced points after the cap is forced into position uponthe body and these projections or lugs engage a shoulder formed by alocking groove in the container body, whereby the cap is firmly held insealing relation to the container by a substantial downward sealingpressure, but may be easily released and reapplied where necessary. i

The container itself is free of seams or joints and with the cap, may beeasily and cheaply formed by means of automatic metal pressingmachinery. 1

Referring to the drawing,

Figure 1 is a front elevation of the container showing the cap or lidapplied;

Figure 2 is as ectional view on the line 2--2 of Figure 1;

Figure 3 is a fragmentary sectional View enlarged and taken on onelcorner of Figure 2; and

Figure 4 is a sectional view partly broken away showing a modified typeof integral bottom.

Referring to Figurel, the container which is made of metal is indicatedas a whole at I0 and includes the cylindrical body II having the integral bottom I2 extending above the plane of the bottom edge I3 of thebody as shown in Figure 2. This construction is formed by bending themetal of the bottom adjacent its periphery upwardly, as shown.

As shown best in Figure 3 and somewhat exaggerated as to size, at itsupper endthe body II is of reduced diameter, as at I4, the metal beingdrawn inwardly as at I5 forming a lid pryoff shoulderl and a groove I6having a locking shoulder I'I produced at the base of the reducedportion. The free edge of the reduced portion is curled inwardlyto forma bead I8 which is preferably hollow and `closed as at I9 and forms asealing lip 20. It will be noted that the body, J

including the bottom and cap receiving portion,

is formed from a single piece of metal and is de vod of seams or joints.

Referring to Figure 2, where the container is drawn to substantially theexact size, it will be noted that the pouring mouth is unobstructed, thebead `I8 substantially merging with the wall of the body, asdistinguished from the usual metal container where the body has ahorizontal inwardly extending flange, the latter acting to retarduniform flow, as well as causng the contents to collect around themouth.

The lid or cap 2| is devoid of seams or joints, being formed of a singlepiece of metal, and has a flat top. At its periphery, the metal of thecap is bent downwardly, as shown at 22, and a sealing' groove is formedby bending the metal upwardly as at 23 and over to produce the integralskirt 24. There is defined between the wall 23 and skirt 24 a groove forreceiving the sealing bead I8 which s reslliently gripped between thewall 23 on one side in metal to metal contact, as shown, and the skirt24 on the other, the skirt, as shown, engaging in metal to metalcontact, a longitudinal area of the reduced neck portion I4 of the body.This assures a very satisfactoryy seal, since the lid and body beingformed of thin, somewhat springy, metal, the substantally dia.- metricalengagement of the walls of the sealing groove with the bead isresilient. The lower edge of the skirt is preferably curled outwardlyinto a. hollow rolled edge 26, as shown.

By reason of the construction of the sealing groove 23--24 and lockingbead I8 whichis received within the same, it is possible to interpose agasket material 21, thereby additionally enhancing the seal, and thissealing material may be coated upon the interior of the groove in thecap or upon the bead I8 or may be separate therefrom.

In forming a sealed package, the cap is forced down over the bead,causing frictional sealing contact on opposite sides of said bead, andis pressed down suiiiciently to compress elastic sealing medium 21,While so held under compression, portions of the rolled edge 26 arepressed in, as shown at 28, at spaced points to form lugs which lock thecap securely in position. In removing the cover it is necessary toinsert a tool under each lug, and using prying shoulder I5 as a fulcrum,bend the lugs back to clear wa1l|4 and then further pry the cap off beadI8. After thus opening the can, the cap is still useful as a frictionalseal around walls 23 and 24. Of course,

Athe lugs could again be bent in again if desired,

to again lock it securely. The cap does not extend axially beyond thebody of the package as shown in Figure 3 and hence does not constitutean obstruction, so there is no danger that it may accidentally beengaged and loosened or priedv off.

In Figure 4, the bottom is likewise integral with the body, but themetal thereof is bent upwardly; as shown at 2S, and then reversely bentdownwardly to a lesser extent, as shown at 30, such construction actingto rigidify the container for certain uses.

As will be appreciated, we have constructed a metal container of twoparts, namely the onepiece body and one-piece lid or cap, each devoidof` seams er joints; unobstructed and uniform flow and complete emptyingof the contents is made possible, and at the same time a very high sealis permanently obtainable, the cap or lid,

however, being easily removable and reusable without destructivedistortion of the body or cap. It is further to be noted that when thecap is applied, its skirt and bead lie within the confines l of the bodyand do not project outwardly to present an obstacle such as might causethe cap to be jarred off in handling or the package damaged.

Various changes and modifications may be made in the construction, allof which are cornprehended in the appended claims.

We claim:-

l. A container having a body and a neck of reduced diameter, the base ofthe neck being bent inwardly to form a locking groove for receiving abead formed in the free end of a cap skirt, the neck having its freeupper end turned inwardly into a completely closed hollow resilient beaddefining the mouth of the container and adapted to be received in alocking groove in the cap, and a cap having a locking groove providedwith a curved bottom and defined thereby and by the cap skirt and adownwardly extending wall formed by a recess in the top of the cap, thecap skirt and said wall being continuous with the curved bottom of thegroove, the walls of the groove so formed being resilient andresiliently gripping the bead withthe Wall of recess engaging the beadtangentially, there being a space between the top of the sealing beadand the bottom of the locking groove to receive a packing, a packinginserted in saidv space, the inner surface of said skirt engaging theouter surface of the neck substantially coextensive with the wallthereof from said point of engagement with the bead to the point ofengagement of the bead on the cap skirt in the locking groove'of theneck, the lower wall of the locking groove in the neck forming a pryoifshoulder for releasing the cap from its resilient locking engagement,the cap skirt when in position lying within the confines of a projectionof the container lbody wall with the bead on the skirt locked inresilient engagement in the locking groove of the neck. h
